Treaty of Hadiach

The Treaty of Hadjatsch was closed on September 16, 1658 in the eastern Ukrainian Hadjatsch between representatives of Poland-Lithuania (p. Bieniewski and K. Jewłaszewski ) and the Ukrainian Saporogerkosaken ( Ivan Wyhowskyj, Yuri Nemyrytsch and Pawlo Teterja ).

The Treaty of Hadjatsch came a year into existence after the death of Hetman Bohdan Khmelnytsky, who had fought bitterly against the Polish crown and Ukraine placed in the Treaty of Perejaslav under protection of the Russian Tsar. Initiated by Chmelnyzkyjs successor Wyhowskyj, the contract provided for a return of the Cossacks in the Polish-Lithuanian aristocratic republic, whereby they should receive the same status as Poland and Lithuania ( in Polish: " Rzeczpospolita Trojga Narodów " - " Republic three nations "). It was also agreed that the Church Union of Brest would be lifted and the Orthodox Church thus should receive the same rights as the Catholic Church.

Although the treaty was ratified by the Polish Sejm, but many of its most important innovations in the ratification among the political autonomy of the Ruthenians, and the equality of the Orthodox Church were canceled unilaterally. The renewed rapprochement with Poland had received in Ukraine a bloody civil war resulted, as the Ruin (Ukrainian Руїна ) in the historiography. This reflects the Cossack elite, the more privileges in the aristocratic republic promised himself and the broad pro-Russian and anti-Polish set of the population were over.

The implementation of the Treaty of Hadjatsch ultimately failed in the overthrow Wyhowskyjs, but also the resistance of the Polish nobility, who saw their privileges in Ukraine in danger.
